The Question
If you want to improve engagement in your organisation, you need to know what actually drives it. "Improve the culture" and "be a better leader" are not actionable. The JD-R model offers a specific, testable framework: engagement rises when job resources are high and falls when hindrance demands dominate. But which resources matter most? And why does high workload sometimes correlate with higher engagement rather than burnout? The meta-analytic evidence now provides clear answers.

The Bottom Line
The Job Demands-Resources model is the dominant evidence-based framework for predicting engagement. Two major meta-analyses — covering 159 independent samples and over 119,000 participants — reveal that not all demands are equal: challenge demands (high workload, time pressure) actually increase engagement, while hindrance demands (bureaucracy, role conflict) decrease it. Among resources, development opportunities show the strongest association with engagement (r = .45), exceeding autonomy, social support, and job-level resources.
